The upper portion of the shank is considerably enlarged diametrically to form an expansion chamber IU of substantial volume, which chamber communicates at its lower end directly with the lower part of the shank, and at its upper end opens through a passage I3, that is approximately equal in diameter to that of the neck of the shank, into the spout proper. This enlargement forms a downwardly facing annular shoulder I4 encircling the shank against which the gasket 8 is seated. v

The spout portion 4 comprises a rather shallow cup-like body with a laterally extended pouring lip I5. Opposite the lip, the body has an outwardly extended Wing I6 to which the thumb piece I8 of a cover I'I is pivotally attached, as seen at Illa. The thumb piece I8 extends beyond the pivot point, and pressure may be applied downwardly thereagainst to lift the coverto its open position, as seen in Fig. 1.

At its under side, the spout body has a somewhat restricted neck portion I9 forming` an annular, outwardly opening channel 2U which receives therein the inturned rim 21| of the upper edge of the collar 5, which is tted about the diametrically enlarged portion Vor expansion chamber I0 of the shank. The lower edge of the collar 5 likewise is crimped inwardly beneath the shoulder I4, which is formed by the diametric enlargement of the shank to provide the chamber I0, thereby to lock the collar in place and to secure all the parts of the device functionally assembled.

One of the features of the invention resides in the fact that a horizontal cross section through the shank just below the shoulders 6 6 is substantially oval in outline; therefore, it is apparent that in pressing the device into place through a can wall opening, a somewhat oblong opening 23 will be formed, as designated in dotted lines in Fig. 4; then by rotation of the device through an angle of 90 the shoulders 6, which are at the opposite sides of the major axis, will be caused to tighten and lock beneath the edges of the opening across its minor axis, thus to lock the device in place. Also by virtue of the inclination of the shoulders these will operate to clamp the sealing gasket 8 tightly against the can Wall.

Another feature of the invention resides in the provision of the expansion chamber I0 whereby all irregularity of flow, as well as the gurgling and air bubbling incident to pouring contents from the can, is eliminated. The explanation for this is not clearly understood but the fact remains that contents may be quickly and readily poured from the can and without the inward bubbling of air or unevenness of flow.

Still another feature of the invention resides in the two-,part construction of the shank which permits these parts to be easily formed in an inexpensive manner, and to be assembled together and about the upper spout portion easily and readily, and then to be secured in place by theapplication of the encircling collar 5. Since the collarv holds these parts tightly together, and is also seated at its lower end against the gasket 8 and at its upper end is sealed about the pouring spout, there is no possible chance of leakage. Y

To insure that the spout portion 4 will not have any turning tendency relative to the shank, the. latter is formed at its top edge with small protuberances 25 adapted to seat in notches 26 in the lower rim of part 4, as seen in Fig. 2.

Devices of this character preferably are made of stainless steel and in the stamping or forming operation the cutting edges are sharpened so that no additional grinding or sharpening is necessary to make them effective. The two pointed end portions of the shank converge, as shown in Fig. 3, below the level of the shoulders. Therefore, the portion removed from the can wall in preparing the opening for the device will be entirely severed. The formation of the shoulders 6 is such that there will not be any abrupt corners, but will provide rounded surfaces that are easily cleaned, thus adding to the sanitary character of the device.

An added feature in the pouring spout is formed at the point of the lip I5 wherein an abrupt downward bend I5a adjacent the lip end effects a no drip result that is exceptionally effective.

Having thus described my invention, whaty I claim as new therein and desire to secure by Letters Patent is 1. A device of the character described, comprising a tubular body, formed at its outer end with an enlarged pouring portion and formed at its inner end with a mounting shank applicable to an opening in a container wall to receive contents from the container, and formed intermediate its inner and outer ends with an enlargement forming an expansion chamber having a restricted opening into the outer end portion.

2. A pouring spout for metal containers, comprising a tubular body formed intermediate its ends with encircling restrictions defining an expansion chamber within the tube; said body terminating at its inner end in a cylindrical shank comprising shearing points adapted to be pressed through a can wall to remove a cylindrical part thereof for reception of the shank; said shank having diametrically opposite shoulders outwardly formed thereon adapted to pass through the opening by outwardly deforming opposite edge portions thereof to provide an oval opening, and adapted, by partial rotation of the shank, to lock beneath the undeformed portions.

3. A pouring spout for cans, having a shank comprising two complemental, semi-cylindricalf 4. A device as in claim 3, wherein there is an upper end pouring section formed about its base with an outwardly opening groove, and wherein the said shank portions are formed at their upper ends with inturned flanges seated within the said groove as a means of locking the parts together, and are held functionally assembled therewith by the said encircling collar. 5. A pouring spout for cans, comprising an outer end portion and a mounting shank; said shank comprising two complemental, semi-cylindrical parts fitted together to form a cylindrical mounting tube for the device and each of said parts being tapered at its inner end to a point adapted for shearing through a can wall to form a mounting opening for the device, and formed attheir outer ends with enlargements tof` gether constituting an expansion chamber in the spout and forming a downwardly facing annular shoulder, for seating a sealing gasket.

6. A device as recited in claim 5, wherein each part of the shank has an outstanding shoulder arranged to operate as a means of seating and retaining the device in place by engagement with the can Wall about the opening.

7. A pouring spout for cans comprising a mounting shank and a tubular outer end portion forming a spout; said shank comprising two complemental semi-cylindrical parts tted together to form a cylindrical mounting tube for the device and each of said parts being tapered at its inner end to a point adapted for shearing through a can Wall to form a mounting opening for the device, and formed at its outer `end with an enlargement; said enlargements being fitted together within the tubular outer end portion and together constituting an expansion chamber Within the spout.

8. A device of the character described, comprising an outer end pouring part formed with an encircling groove about its base, a shank comprising opposite side parts fitted together to form a cylindrical mounting tube for the device and enlarged to cooperate in forming an expansion chamber beneath the outer end portion, a collar fitted about the shank enlargement and having its edges clamped, respectively, beneath the enlargement and into said encircling groove of the outer end part to hold the parts functionally assembled; said outer end part having `notches in its lower edge portion and said shank parts having extensions seated in said notches to prevent relative rotative movement of the 15 shank and the outer end part.
